PRINCIPAL OF OPERATION
These are oil-immersed, rotary vane type pumps. The rotor, with two spring loaded vanes, is mounted eccentric in the stator body, As the rotor, rotates the vanes sweep the creascent shapes, air space twice in each revolution. There is in-built non-return valve which prevents back flow parts are precisely machined, ground and assembled with close tolerances. This result in increased efficiency and long trouble free operating life.

ACCESSORIES


*Air Ballast: Optional
This is a vent pipe introducing air before actual compression which eliminates condensation of the sucked vapour, Their by avoiding contamination of oil.

*Air admittanc valve: Optional
It is electromagnetic solenoid type which admits air into the system as soon as the power supply fails. This prevents back-flow of oil to system.

*Non-return valve:inbuilt
It is rubber diapharm type, spring loaded valve, Which prevents back-flow of oil to system as soon as pumps stops. There can be used to hold the vacuum in the system for longer period.

 *moisture trap

*Inlet Dust Filter

*Vacuum Gauge With Regulatorr

*Trolly for Small Pumps-Optional

*USE OIL :ENCLO-46(H.P)/SAE -30 Or Equivalent.

*Model GHV-300-ll and above are provided with water cooling jacket.

*Vacuum measured Mcleod gauge at port of the pump.
